LUMINoUs PEN on PENCIL.

Specification of Letters Patent.

Patented May 20, 1919.

Application filed July 24, 1918. Serial No. 246,463.

the following description, in connection with the accompanying drawings,is a specification, like characters on the drawings representing likeparts.

rIhis invention relates to luminous fountain pens and pencils.

The primary object of myinvention is to provide a fountain pen or pencilcontaining, Inova-bly attached Within the body thereof, a small electricilluminator which can be readily raised so that the illuminator isbrought without the barrel or body of the fountain pen or pencil,whereby it may be used for diffusing light upon a pad or paper bydoctors and nurses when writing prescriptions or reports in the sickroom, and the like, and by military oiiicers in the field when a readyat handsubdued light is required, and other illumination diiiicult orimpossible.

A further object is to provide a small portable pocket electricilluminator for use by doctors and surgeons for diagnostical purposes,and as an emergency light in rendering first aid and performing minoroperations in the ield where other illumination is not at hand ordiiicult. l l

A. further object is to provide a small portable pocket electricilluminator for use by autoists as a miniature trouble light.

Nu meral 25 indicates holes in portions ofthe socket member bentand formed so as to form a hinge. Numeral 26 indicates the opening inthe end of the-pen or pencil barrel or case for introducing primary andsecondary battery wires. Numeral 27 indicates the position at which oneof the battery wires is soldered and secured to the end of the barrel orcase. Numeral 28 indica-tes the position at which the remaining batterywire is soldered andV secured to the end of the cylindrical cuppedcontact switch. Numeral 29 indicates the partition which separates theportion of the main barrel or case containing the pencil or fountain penink from the rear portion of the barrel which contains the illuminatingdevice. yNumeral 30 indicates an oblong opening in the main case orbarrel of the pen or pencil, which is adapted to be closed by a portionof the socket member. Numeral 3l indicates a cylindrical cup memberforming the rear end of the pen or pencil. Numeral 32 indicatesperforated tongs or cleats formed integral with the socket member 2 forattaching the same to the mam case hinge fashion, by means of a rivet 9.Numeral 33 represents the retaining ends of the tongs or cleats 22.

The main barrel or case 1 is preferably formed of cylindrical metaltubing, in one end of which the tapering pen or pencll member 17 isremovably attached, and the other end of which is closed by anirremovable tubular cup member 31. An oblong opening 30 is provided inthe main barrel or case adapted to be closed by a. portion of the socketmember, having its end 21 beveled or tapered so as to give purchase withthe end of a finger nail when it is desired to raise the socket memberand to facilitate which operation a. small space 35 is left between theend 21 of the socket member and the main barrel or case of the device.

When the socket member 2 has been raised into operative position as inFig. 2, the point or end 13 of the contact wire 4 is brought intocontact relation with one side of the cylindrical cupped contact switch6.

The rivet 9 passes through the case or barrel near the diameter, andalso through the holes 25 or openings in the socket member 2, being atall times in contact with both members.

The electric bulb engages one end 14 of the contact wire 4 and the outercase 10 of the electric bulb engages at all times the threaded opening2O of the socket member 2, so that when the socket member is raised intooperative position, as indicated in Fig. 2, with the end 13 of thecontact wire t resting upon the side of the cylindrical switch member 6,and the wires 7 and 8 are attached to a battery in the customary way,the electric circuit is closed and electric current is imparted to theelectric bulb whereby it is caused to glow and emit light as indicated.

vIt will be noted by this arrangement of parts that the mere raising ofthe socket member 2, as indicated in Fig. 2, closes the contact andthrows on the electric current and by merely lowering thc socket member2 into the main barrel or case of the device, the end of the contactwire 13 is raised from contact with the cylindrical switch member 6,whereby the circuit is opened and the contact broken and the electriccurrent cut 0H.

It will also be noted that the insulation 3 of the contactwire preventsthe 4contact wire from touching the socket member 2l and the insulation5 prevents the tubular contact switch member 6 from touching the endmember of the case 31.

As will be seen from the drawings, the wires 7 and 8 are introduced intothe end of the case member 31 through a suitable opening 26 providedtherein.

,1n practice the socket member 2 is preferably formed of one piece ofsuitable metal having three tongs or cleats on each side, the end cleats32 capable of being bent at right angles forming a hinge, and the tongsorl cleats 22 bent at right angles with the ends 33 bent down over theinsulation 3 so as to firmly grip and retain the same, and the other endof the socket member 2` is formed loop fashion, and bent upon itself at24ras in Fig. 3, a portion thereof, 11, having cylindrical formationlongitudinally describing a section of the main body member, and adaptedto operate in the opening therein freely so that when the member isclosed, as in Fig. 1, with the under portion resting upon the inner wallof the main case, it completely closes the opening 30 in the mainmember, except for the small space at one end 35, so that the outersurface of the device is substantially uniform.

The circumference of the end of the main case is uniformly reduceddovetail fashioned at 12 the thickness of the wall ofthe main case, forthe purpose of seating the end portion 31, the edge of which, when inplace, is knurled or otherwise 'slightly de pressed so as to firmly andpermanently grip and close the end of the main case 1.

The circular disk or partition 29 made of metal, rubber or othersuitable material, is irremovably introduced' and sealed in the barrelof the main case before assembling, whereby the front portionv or endofthe main case is tightly sealed and'suitab'le for retaining ink orother fluid.

It will be noted that inthis vdevicethe need for throwing on current bythe battery case switch, in the customary way, is obviated, and for adevice of this description desirable to be carried in theV pocket wherea pocket clip is not desirable or adaptable, this device offers unusualfeatures, that cannot readily be made available in Lany other way. f IIt will also be understood 'that theend 17 may be formed so as to employany standard, usable, permissible and adjustable lead pencil device orpermissible fountain pen device, so that the main device may be madeeither to be used as an illuminated pen or as an illuminated leadpencil.

Having thus described my said improvement, I claim as my invention anddesire to secure by Letters Patent under this specification:

l. A tubular casing adapted to hold a pen or pencil having an opening inthe body thereof, an electric bulb attached within the opening hingefashion, capable of being raised or movedl to a position outside thesaid opening, suitable Wire or metal connections for attaching thetubular casing to an electric battery whereby electric current may beimparted to the electric bulb so as to cause it to glow andimpart light.

2. A tubular casing adapted to holda pen or pencil having an opening inthe body thereof, an electric bulb attached within the body, hingefashion, capable of being raised or moved to a position outside the saidopening, a contact switch adapted to be engaged and closed by theraising of the electric bulb and opened by the lowering of the electricbulb, suitable wire or metal connections for attaching the tubularcasing to an electric battery whereby electric current may be impartedto the electric bulb so as to cause it to glow and emit light forluminating purposes.

3. A tubular casing adapted to hold a pen or pencil, having a recess inthe body there- Copies o1' this patent may be obtained for five centseach, by addressing the of, a hinged socket member movably attachedtherein, adapted for holding a small electric light bulb, and formed toclose the opening in the main member, insulated wire means and switchcontact means suitable for conveying electric current.

4.

5. The combination of a tubular casing, adapted to hold a pen, an inkchamber and tubular means extending therefrom to the pen for supplyingink thereto, a socket for holding an electric bulb, movably retainedwithin a recess in the casing, insulated electric switch means at oneend of the casing, suitable insulated wires for supplying electriccurrent from a battery to the electric bulb, all substantially asdescribed and illustrated in the drawing.
